The devastating 2015 floods contributed to 19 deaths and crippled parts of the capital city Columbia for months. The state's infrastructure, weakened by years of neglect, crumbled under the strain of nearly 2 feet (60 centimeters) of rain. Dams burst across the state.

South Carolina has 42,000 miles of state-maintained roads, according to the state Department of Transportation.

Spokesman Pete Poore says the agency is positioning crews of its 3,200 maintenance workers across the state to be ready to fix broken traffic signals, barricade problem areas and do whatever else is needed to make the state's roads safe again after Florence.
